HAMMER.

To all whom it may concern Be it known that I, WILLIAM H. SWIFT, a citizen of the United States, and a resident of the city of New York, of the borough of Brooklyn, countyof Kings, and New York, have invented certain new and useful Improvements in Hammers, of which the following is a specification.

My invention relates in general to an improved means for fastening a handle to a tool and specifically relates to a means for fastening a helve to a hammer head. An object of my invention is to provide a secure and positive connection between the helve and tool head which will eliminate any possibility of the tool head flying off the helve during use but which will permit the ready separation of the parts when desired.

Various other objects and advantages will be apparent from the following description of one form of physical embodiment of the invention which consists broadly in inserting a helve in the eye of a hammer head or other tool and drawing a wedging band can ried by the head into binding engagement with the helve transversely of the same. The invention further consists in other details of construction hereinafter set forth and claimed.

In the drawings Figure 1 is a side elevation of a hammer disclosing a preferred embodiment of my invention.

Fig. 2 is a similar View with the head and adjacent portion of the helve in longi tudinal section.

Fig. 3 is a perspective view of the hammer head detached from the helve.

Fig. 4 is a perspective view of the wedging band.

Fig. 5 is a side View of the wedge screw.

Fig. 6 is a longitudinal sectional view through a slightly modified form of hammer head, and- Fig. 7 is a perspective view of the hammer head shown in Fig.

In the drawings is shown a hammer head 1 into the eye'2 of which is inserted a helve 3 as is usual with devices of this character. An extension 4: from the hammer head outlines a portion of the eye 2 which extension carries a band 5, the eye 6 of which is broader at one end than at the other and Specification of Izetters Patent.

State of B'passing through the The side Patented May 6', 1919.

encircles the portion of the helve above the extension 4:. A screw 7 is threaded through the portion of end of the eye 6 and' has an unthreaded pin extension 4- and seatlng within a socket 9 inthe helve 3. To hold the band 5 in place a rear wall 10 is affixed to the extension 4, preferably integral therewith, which wall has a crotch 11. adapted to straddle the helve.

eferring to the modification shown in Fig 6, the wall 10 is omitted and a tooth 12 pro ects into the eye 6 from the portion of the band 5 containing the small end of the eye, and is adapted to bite into the helve or to seat in a recess 13 formed in this portion of the helve. As the tooth is drawn into the wood of. the helve, the opposite side-0f the band will be drawn awayfrom the extension 4t forming a space I l therebetween.

In operation one side of the band defin ing the wide portion of the eye 6 is passed over the wall 10 with the ring extending at right angles to its final set position and with the eye facing in the direction of the length of the wall or vertically when the hammer head is in the position shownin Fig. 3. of the ring between the wall 10 and the hammer head is then allowed to drop down on the extension 4., which will cause the ring to turn and swing the side of the ring which was outside of the wall 10 down under the lower end of this wall. The ring is then rotated about an axis paralleling the length of the helve thus bringing the ring into the position shown in Figs. 1., 2 and 6, the helve is inserted through the eye 6 into the eye 2 and by tightening up the screw 7 the band 5 will be drawn transversely of the litngth of the helve into firm binding engagement with the sides of the helve. The unthreaded portion 8 of the screw 7 prevents any relative movement between the helve and hammer head and retains the band in set positionrelative to the head while the screw portion 7 permits the drawing of the band 5 into wedging engagement with the helve with any desired force and it is even possible to hammer the band 5.into wedging the band in this wedging position by means of the screw 7.

The rear wall 10 prevents the band 6 from slipping off the head longitudinally of the position and to loclc the band 5 having the wide helve and in the modification shown in Fig. 6 this same function is provided by the tooth 12.

Although I have shown one form of mechanism embodying my invention, it is obvious that various changes within the knowledge of those skilled in the art can be made therein without departing from the spirit of the invention provided the means set forth in the following claims be employed.

Having thus described my invention, 1 claim 1. The combination with a tool head having'an eye and a helve insertible therein, of a wedging member in the form of a closed ring carried by the'head surrounding the helve and movable bodily into engagement with said helve transversely of the length of thef'helve.

2. The combination with a tool head, a helve insertible therein and having a socket in one side and a recess in its opposite-side, a band encircling said helve and having a portion insertible in said recess and a holding member passing through said head and positioned in said socket.

3. In a device of the class described, the combination of a hammer head provided withaneye, said head having an extension outlining a portion of the eye, a band having an opening therethrough broader at one end than at the other, and encircling the extension, a helve adapted to be inserted Copies of this patent may be obtained for five portion of the eye, a rear wall through said eye and opening and a screw extending through helve for drawing theban'd into binding engagement with the helve.

4. In a device of the class described, the combination of a hammer head provided with an eye, said head having an extension outlining a portion of the eye, a band having an opening therethrough broader at one end than at the other and encircling the extension, a helve adapted to be inserted through said eye and opening and means for guidingsaid band in its movement into engagement with the helve.

5. In a device of the class described, the combination of a tool provided with a helve eye, and having an extension fixed to said extension and coacting with saidhead to form a band containing groove, a band in the form of a closed ring having a portion disposed in said groove and a portion designed to engage the tool helve when inserted in said eyeand means acting on the band for drawing the same into binding engagement with the helve.
